APPARATUS FOR ADMINISTERING OXYGEN OR THE LIKE.

I r Application filed January 6,1908.

This invention relates to certain improvements in apparatus foradministering oxygen and other vapors by inhalation, and enabling thesame to be taken in a cold moist, cold dry, hot moist or hot drycondition.

The objects of the invention are to provide an improved means foradministering and heating oxygen; to provide improved storage meanswhereby prescribed quantities of oxygen may be stored and heated tosecure for these purposes means which can be read ily combined with theusual containing cylinder, either permanently or temporarily; to providea compact and efficient construction, which is strong, durable andinexpensive; to thus facilitate and simplify the administering of gasesand vapors, and to obtain other advantages and results as may be broughtout in the following description.

Referring to the accompanying drawings, in which like numerals ofreference indicate the same parts in the several figures, Figure 1 3,looking in the direction indicated by the arrow Fig. 5 is a planillustratinga certain storage tank; Fig. 6is a detail view of a certainwasher; Fig. 7 is a side elevation of a three-way pipe connection andassociated parts thereof, partly in section on line y, Fig. 2, lookingin the direction indicated by the arrow; Fig. 8 illustrates an improvedmouth piece, and Fig. 9 is a side view showing the use of said mouthpiece.

In said drawings, 1 indicates the body portion of my improved device inits preferred form and adapted to be placed on the top of a gas cylinder2 charged with oxygen or other vapor. The said device comprises an outercasing 3 and a storage tank 4, the said tank being of an air-tightconstruction and for the vpurpose of storin prescribed quantities ofoxygen. The tan 1 4 is raised off the bottom Specification of LettersPatent.

5 of the outer casing by means of feet 6,(see Fig. 4), and isconstructed somewhat smaller than the outer casing 3, so as to provideample space at its bottom and sides to form a water jacket 7, wherebythe oxygen in the tank may be heated or warmed by pouring hot watertherein. If hot water cannot be obtained, cold water may be used andheated by means of the gas burner 8 beneath the bottom 5 of the casing,set on the cylinder 2 and connected by a tube 9 to any suitable gassupply.

The outer casing 3, of my improved device comprises walls 10 of sheetmetal, and the bottom 5 which is sufiiciently above the lower edges ofthe said walls to provide a flange or skirt 11 adapted to fit onto therounded upper end or top of the cylinder 2. At the front of my improveddevice, both the casin 3 and the inner storage tank 4 are flattene orcut away on a chordal plane, as shown in Figs. 2, 3 and 5, at 12, 13.For this portion of the casing 3, its flange or skirt is cut away as at14, and the rest of the way around the 'casing said skirt or flange hasapertures 15.

Preferably, one of these apertures is used to pass a bolt through intoabracket 16 which has its other arm bolted or screwed to the top of thecylinder 2, and serves to connect the device 1 to the cylinder when madeseparate as shown. If preferred, the device 1 can be made integral withthe cylinder.

The oxygen is taken from an outlet 17 of the cylinder 2 by means of apipe 18 which extends 11 Ward and bends in over the to of the cylin erto lie in front of the flattene or recessed portion of the body 1, asshown. A valve 19 is in the lower part of this pipe, and when this valveis o ened by means of a key upon the delivery 0 the apparatus, theoxygen will pass up through the pipe 20. To the top of a four-waycoupling 23 at the top of said pipe 20, is connected a gage 21, and fromwhich the pressure in pounds of the gas contained in the tank may beascertained by referring to the indicator 22; the number of gallons ofgas iii the cylinder may also be recorded by constructing the cylinderof such size that a gallon will e ual one pound pressure. For othersizes 0 cylinder, a separate scale of gallons could be marked on thesame gage.

Of the other two arms of the four-way coupling 23, one as 24 isordinarily closed by a screw plug 25 which however can be removed at thefactory for filling the cylinder.

the tube at this point.

The opposite arm of the four-way coupling is connected to a stop cock orvalve 26, and beyond said valve is a three-way coupling 27, one of whosearms is directed upward and the other toward the device 1. From thislastmentioned arm of the three-way coupling, an exteriorly threaded pipe28 leads through the walls of the outer casing 3 and of the storage tank4, screwing into an inwardly projecting socket 29 on the wall of thetank. The end of this socket has a stop or flange 30 bent radiallyinward, and between said flange and the end of the pipe 31 is compresseda gasket 32 to secure greater imperviou-sness.

Since the pipe 28 passes through the water jacket 7, a resilient washer33 also surrounds the pipe at this point, and is adapted to be pinchedtight between the storage tank and outer casing by a nut 34 screwed onthe pipe 28 against the outside of said outer casing. Thus to fill thestorage tank 4, the valve 26 is opened and the oxygen passes into thetank through said valve, the threeway coupling 27 and the pipe 28, asindicated by the arrow.

When the desired amount, as indicated by the gage 21, usually fivegallons, has passed into the storage tank, the valve 26 is closed, andthe oxygen may then be heated as hereinbefore described. After heatingto the desired temperature, the oxygen may be administered to thepatient, and the means by which the gas leaves the storage tank willnext be described. An outlet tube 35 of considerably smaller diameterthan the inlet pipe 28 and its opening into the storage tank, leadsoutward centrally through the same, and in the three-way coupling 27 isbent upward and has its end held in a plug 36 which otherwise closes theupwardly leading arm of the three-way coupling. This outlet tube 35preferably extends into the tank for a considerable distance beyond theinlet 37, as at 38, so as to take the oxygen from the storage tank at adistance from the inlet. This con struction is particularly desired whenboth valves 26 and 39 are opened and a continued supply of oxygen isadministered to a patient, as the cold oxygen will become heated in itstravel through the storage tank to the outlet 38 of the tube 35.

From the upper arm of the three-way coupling 27, a flexible tube 40leads to a mouth-piece 41 which may be of any suitable and well-knownform. A coiled spring 42 is mounted on the secured end of the tube asshown at 43, Fig. 1, to prevent the tube from bending flatwise and toprovide an unobstructed annular interior channel in A valve or stop-cock39 is provided just above the upright arm of the three-way coupling 27,so as to control the supply of gas through the discharge tube 40 to thepatient, if desired. I prefer, however, to

always make the outlet tube 35 from the storage tank of such size thatno more can escape through it than a patient can safely take.

When moist oxygen has been prescribed and is desired to be administered,a wash bottle 44 is employed, (see Figs. 1, 2, 3 and 4). Said bottle isplaced in a central space or chamber 45 of the storage tank said chamberextending through from top to bottom of the said tank, and the bottlestanding upon an annular inwardly projecting flange 46 at the bottom ofthe tank. The bottom of the bottle is thus exposed, and said bottle isfurthermore smaller in diameter than its chamber 45, so that water canflow around it from the water-jacket; resilient washers 47 on theoutside of the body portion 48 of the said bottle hold it central in thechamber, said washers being provided with. notches 49, 49 to permit thepassage of water so as to heat the contents of the bottle and alsoassist in heating the storage tank. The mouth of the bottle 44 istightly closed by a stopper 50 through which two tubes 51. and 52extend, one as 52, nearly to the bottom of the bottle and the other 51only just through the stopper 50. The outer ends of both tubes 51 and 52are bent laterally, and in use the supply hose 40 is removed. from itsposition first above described and slipped onto the short tube 51 of thebottle, while another short piece of hose 53 is used. to connect thedischarge pipe of the supply tank 4 to the long tube of the bottle, allas shown in dotted lines in Fig. 1.

By the above arrangement, the bottle 4-! being partly filled with water,the gas before going to the patient will bubble through sai l water andbe rendered moist, and this whether it is hot or cold. Furthermore.drugs or medicines can be put in the said bottle and also administeredto the patient with the gas.

Preferably, the top of the storage tank is dished or centrallydepressed, as shown at 54 in Figs. 3, 4 and 5, whereby the opera tion ofthe bottle 44 may be more clearly observed when in use, and also agreater heating area of both oxygen tank and water jacket secured. Tofurther facilitate ohserving the action of the gas in the bottle, thecover 55 for the casing 3, as shown in Fig. 2, is open from its frontedge to its center, or slotted, as at 56.

A valve or pet cock 57 in the wall 12 of the outer casing 3 and at thebottom of the water jacket, is for the purpose of drawing the water fromthe same. It will also he noted that the piping projecting from the icylinder 2 at the valve 18, affords a handle 58 by which the device andcylinder may be grasped.

For administering oxygen to a patient in an unconscious condition orunable to hold the mouth piece41- I have provided a funnel 60 which maybe screwed into theiend of the tube 40 in place of the mouth piece 41,said cap'having at one side a recess 61 in its edge to permit its beingheld over the mouth as shown in full lines-in Fig. 9 or over the mouthand noseas shown in dotted lines in the same figure.

It will be understood that in filling the water jacket between thestorage tank 4 and outer casing 3, enough is poured in so that its levelstands a considerable distance up the top sloping annular surface of thestorage tank, as shown at 62 in Fig. 4. This affords a considerable bodyof water, and at the same time gives large area of surface contact withthe tank.

The storage tank 4, it will be understood, may be made of sheet steel,and after the manner of the cylinder 2, so as to withstand the samepressure as said cylinder, or it may be constructed in any othersuitable manner.
